Russian and foreign epidemiological data suggest that males may have an increased risk of morbidity and mortality associated with COVID‑19. It is known that due to the high expression of ACE2 in spermatogonia, Leydig and Sertoli cells, the testicle, as an organ producing male germ cells, is a potential target for the COVID‑19 virus, which directly affects the reproductive health of men. To date, several factors of the influence of the SARS-CoV‑2 virus on the male reproductive system are known. To begin with, when infected, the virus has a direct damaging effect on the testicle itself with the provocation of orchitis. In addition to the previous statement, high body temperature during inflammation contributes to an increase in testicular temperature, which can lead to a deterioration in the quality of sperm. Furthermore, a pronounced inflammatory reaction promotes the circulation of a large number of cytokines and damage to the hemato-testicular barrier. Also, the increased activity of immunocytes leads to an imbalance of the antioxidant system of men, an increase in the level of reactive oxygen species and the formation of oxidative stress. In a Nutshell, Leydig cell dystrophy provokes the development of secondary hypogonadism. Thus, COVID‑19, like a “multifaceted Janus”, has a polysymptomatic manifestation, but at the same time has a multifactorial effect on the reproductive function of a man. All these factors of the impact of the SARS-CoV‑2 virus on the testicle must be considered when rehabilitating the patient. It should be kept in mind that the deterioration of sperm quality is observed both during the acute period of coronavirus infection and during recovery period. Therefore, laboratory evaluation of the ejaculate in dynamics and its correction is necessary for males, especially those who plan to realize their reproductive potential.Conclusion. COVID‑19 generally has a negative impact on spermatogenesis and male fertility. To date, the timing and degree of restoration of a man’s reproductive function after a coronavirus infection remains completely unknown. Therefore, both in the early and late rehabilitation period, men of reproductive age need the supervision of an andrologist. |
